The answer is D. Identity of an element is determined by the number of protons, also called the Atomic Number. On the periodic table the atomic number is found above the element name. If you take away or add a proton, the element is not the same element anymore

Leona [35]

One difference between cancer cells and normal cells is that cancer cells continue to divide even when they are tightly packed together (option C).

<h3>What are cancer cells?</h3>

Cancer is a disease in which the cells of a tissue undergo uncontrolled (and often rapid) proliferation.

When normal cells become cancerous, they lose the ability to regulate cell division, hence, they continue to divide excessively.

Normal cells are characterized by their ability to regulate cell division during the cell cycle.

Therefore, one difference between cancer cells and normal cells is that cancer cells continue to divide even when they are tightly packed together.

kodGreya [7K]

Answer:

A mutation in Ras protein which will cause hyperactivity will eventually lead to cancer.

Explanation:

Ras protein was first discovered in Rous sarcoma virus (RSV) and it is a proto-oncogene product. In normal conditions, it plays an important role in cellular signalling but in case of gain of function/hyperactivity it gets converted into cellular oncogene. In several types of cancers a point mutation has been reported in Ras protein.

Just like G protein, it is also a GTPase switch protein but unlike G protein which is trimeric, it is monomeric. In the plasma membrane, it is attached with the help of lipids like prenyl or palmitoyl groups. During signal transduction pathway when it gets activated, it downstream activates MAPK pathway and causes gene expression but when it gets hyperactivated it causes over expression of genes leading to cancer.
